If i have depression, do you think im capable of doing this stuffs?

I always party, go to clubs, hang out with my friends, BUT im not myself.. I know its not me but i do enjoy it, yes because i feel superior and high with all these things im doing.. but its not really the happy type of hanging out.. more like a gang night out / party / hang out whatever. I hope you get what i mean. I cant say that im happy, but i enjoy it. So.. do u think i might be depressed or underyling dep?
